How/In what way does climate change (increasing global temperatures) affect the Water Cycle?

I have two questions actually, one concerning Oxygen levels in the atmosphere while the other one concerning Carbon Dioxide levels. a) How does burning of rainforests, or burning in general, affect oxygen levels in the atmosphere? b) How would the addition of phosphorous and nitrogen fertilizer to the ocean help reduce its carbon dioxide levels? And what problems would adding the fertilizer cause?

Thanks a lot for the help!

What is the difference between a parasite and symbiotic organism? =)

I am currently a Gr10 Science student, and we are currently learning about soil. Does anyone have any idea on how to calculate soil's air content? Much help is appreciated. Thanks!
